Walter began his career shooting for Sports Illustrated and has contributed to the magazine for more than 50 years. He has also photographed for the magazine's Swimsuit Issue for four decades.
From 1968 through 1972, Walter was an in-house photographer for Atlantic Records in New York, where his subjects included performers like James Brown, Jimi Hendrix and Janis Joplin.
In 1982, Walter was recruited by “Fujifilm” to take pictures of athletes who were working their way to the 1984 Summer Olympics in Los Angeles. The two-and-a-half-year project required him to leave his position on the staff of Sports Illustrated (though he continued to contribute) and resulted in the publication of the book “Shooting for the Gold.”
In the late 1980s, Walter was commissioned to photograph advertising campaigns for “Camel cigarettes”
In 1993, Walter’s work was featured on 27 baseball cards in an Upper Deck set named "The Iooss Collection.”
